As you may know Bitmark uses the Bitcoin codebase adapted for Scrypt, we also have a forkable project Pfennig which can be used for new projects.
Recently I swapped
GameCredits GMC from an old Litecoin code base (modified 0.8.x) to the Bitcoin 0.9.4 codebase, successfully.
This gives an opportunity for other coins with older codebases and problems, to be moved to a shared codebase using Pfennig, which is maintained and up to date. In this manner many different coins could all be updated with Bitcoin Core upgrades over time, lowering overhead to maintain, increasing reliability, and making alt coin advancements easier to port back to Bitcoin in the future should they be adopted.
Currently Scrypt with traditional diff, or KGW are supported by pfennig. More adaptations could be added in different branches.
Any scrypt coin could be moved over to it, including litecoin itself.
If you know of any candidate coins or communities which may benefit from this, or have any questions, please let me know. I have limited availability currently to do the codebase swaps myself, but may have ability in the future if anybody would like to employ me to do this for them.
